Sure, >>8947855, here's one of my renders. Spoilers: I like feet.

And I've decided constant interpolation definitely helps with blocking/breakdowns from what I've seen, it's kind of like the animation equivalent of artists who mirror their work regularly while they work on it- it gives you a very un-sugarcoated view of how your poses look in a classic flipbook illustratiion before you try to add frames inbetween.

That's another thing I didn't realize before getting into this: I always assumed the curves (spline or whatever) did most of the work, but no, you have to manually pose and move your characters every couple frames, because the computer's interpolation does *not* understand that stuff is supposed to curve nicely as it moves instead of tweening directly from one position to the next.

Also thanks OP for Mustard Simplify, I had a few rigs that were unusable performance-wise and it helps a lot for both animating and viewing the animation without doing a playblast/render.
